This paper considers the structure of freshwater phytoplankton assemblages and promotes a scheme ‘vegetation recognition', based upon functional associations species represented in plankton. These groups are often polyphyletic, recognizing commonly shared adaptive features, rather than common phylogeny, to be key ecological driver. Thirty-one such outlined basic pattern their distinctive ecologies is outlined. An invitation other plankton scientists assist development this issued.
In this overview (introductory article to a special issue including 14 papers), we consider all main types of natural and artificial inland freshwater habitas (fwh). For each type, identify the biodiversity patterns ecological features, human impacts on system environmental issues, discuss ways use information improve stewardship. Examples selected key biodiversity/ecological features (habitat type): narrow endemics, sensitive (groundwater GDEs); crenobionts, LIHRes (springs); unidirectional...
Summary Ecologists often group organisms based on similar biological traits or taxonomic criteria. However, the use of taxonomy in ecology has many drawbacks because taxa may include species with very different ecological adaptations. Further, characters evolve independently lineages. In this review, we examine main criteria that have been used identification nine modes classifying phytoplankton non‐taxonomically. These approaches are purely morphological and/or structural traits, more...
Phytoplankton, the ecological group of microalgae adapted to live in apparent suspension water masses, is much more than an ecosystem's engineer. In this opinion paper, we use our experience as phytoplankton ecologists list and highlight services provided by phytoplankton, trying demonstrate how their activity fundamental regulate sustain Life on Planet. Although number produced can be considered less numerous that other photosynthetic organisms, ubiquity thriving across oceanic ecosystems...
Abstract Trait‐based ecology has already revealed main independent axes of trait variation defining spaces that summarize plant adaptive strategies, but often ignoring intraspecific variability (ITV). By using empirical ITV‐level data for two dimensions leaf form and function 167 species across five habitat types (coastal dunes, forests, grasslands, heathlands, wetlands) in the Italian peninsula, we found ITV: (i) rotated define space; (ii) increased variance explained by these (iii)...
A renewed interest in investigating the relationships existing between body size and environmental variables is pervading ecological studies. Phytoplankton has a long tradition as model system studies of community ecology several research concepts were developed using these organisms. In this paper we try to review relevance analyzing morphological features phytoplankton ecology. Starting with brief account allometric phytoplankton, i) examine physical context which grow, ii) highlight role...
Abstract There is hardly any sunshine exposed surface on this Earth, be it water or terrain, which would not support some biota. Still, many habitats offer harsh conditions requiring specialized physiological adaptations to survive. These environments are referred as extremes; often inhabited by extremophilic organisms. In review, characteristic species and assemblage properties of phytoplankton inhabiting extreme (especially lakes pools where planktic life potentially possible independently...
Summary 1. Equilibrium and non‐equilibrium hypotheses have often been used to explain observations in community ecology. Published case studies demonstrated that steady state phytoplankton assemblages are more likely occur deep lakes than shallow mixed ones. 2. Phytoplankton seasonal succession was studied by weekly sampling Faxinal Reservoir (S Brazil), a subtropical deep, clear, warm monomictic slightly eutrophic reservoir. This study an alternation of non‐steady phases with different...
Abstract Sicilian reservoirs constitute the most important water resources available on island. During summer 2001, intense utilization of Lake Arancio reservoir reduced level significantly, which coincided with formation blooms formed by microcystin (MC)‐producing cyanobacterium Microcystis aeruginosa . 2003, was continuously filled and vertical stratification column maintained resulting in five to sixfold lower cell numbers M. For both years, a significant relationship between MC net...
Phytoplankton requires a sufficient supply of light and nutrients to grow. At the same time it is largely entrained in water motion subject grazing from planktonic herbivores. The pelagic life lake phytoplankton based on 4 pillars: living suspension, harvesting, nutrient uptake, escape grazing. Environmental variability uneven distribution resources among within different aquatic ecosystems exert selective pressure these organisms, which are formed by single cell or colonies with either...
The influence of filter-feeding bivalves on plankton communities, nutrients, and water quality in a given aquatic ecosystem is so profound that they can be considered engineers. In 70-day mesocosm experiment, we tested the hypothesis Corbicula fluminea would change community structure by reducing small zooplankton large phytoplankton improve nutrients. We monitored levels nitrogen phosphorus, organic suspended solids (OSS), light at sediment surface. Within plankton, biomass (as Chl a,...
Abstract The analysis of ecological niche is an important task to correctly identify the role exerted by species within ecosystems, assess their vulnerability, plan effective measures addressed at fulfilling postulates biological conservation, and ultimately prevent biodiversity loss. However, for majority organisms our knowledge about actual extent quite limited. This especially true microscopic organisms. Evidence exists that in different geographical areas allegedly conspecific...
